I. Product Overview:
The Organic Fertilizer Classifier is a key piece of equipment used in fertilizer production lines for particle size classification, quality screening, and precision control of granular fertilizers. Its primary function is to separate finished organic fertilizer into three categories—qualified granules, oversized particles, and fine powders—based on particle size. This ensures uniform granule size, attractive appearance, and compliance with national or corporate quality standards. The machine is widely applied in the production of organic fertilizers, bio-organic fertilizers, organic–inorganic compound fertilizers, and compost granules, serving as an indispensable process in commercial fertilizer manufacturing.
In modern organic fertilizer production, raw materials are diverse, and particle characteristics vary significantly. After granulation and drying, inconsistency in particle size is a common problem. The use of an organic fertilizer classifier significantly improves product uniformity, reduces recycling rates, enhances production efficiency, and increases product value. With the advancement of agricultural mechanization and intelligent manufacturing, classifiers are evolving toward higher automation, energy efficiency, and smart monitoring—becoming essential equipment for achieving precision and standardized production in modern fertilizer plants.
II. Working Principle:
The core working principle of the organic fertilizer classifier is a combination of mechanical screening and aerodynamic separation, enabling automatic classification of particles of different sizes. Depending on its structural design, the equipment is generally divided into drum-type and vibrating-type classifiers.
The drum classifier consists of a cylindrical screen, drive unit, support frame, and feeding/discharge system. During operation, the drum rotates slowly, and the interior is fitted with multiple screening sections or mesh layers of varying apertures. Material fed into the inlet moves with the rotating drum, rolling continuously—fine particles pass through smaller holes and fall into lower layers or discharge outlets, while larger granules roll forward and exit from the drum’s end. By adjusting the screen aperture and drum speed, precise grading of organic fertilizer can be achieved.
The vibrating classifier uses a vibration motor as the power source. Eccentric blocks generate composite vibratory forces that cause the screen surface to oscillate periodically. Materials move forward in a hopping motion under vibration, allowing fine particles to pass through the mesh while coarser ones remain on the screen surface for further separation. By controlling vibration amplitude, frequency, and screen layers, high-precision classification can be realized.
(3) Airflow Separation System
Advanced models are equipped with an airflow separation system to handle materials containing lightweight organic dust. Adjustable airflow channels utilize differences in material density to automatically remove light impurities, enhancing product purity and appearance.
The entire classification process operates continuously and stably, and can be integrated with cooling and packaging systems for automated and intelligent control throughout the production line.
III. Product Applications:
The organic fertilizer classifier is suitable for grading various granular and powdered materials, with typical applications including:
1. Organic Fertilizer Production Lines – Used after granulation, drying, and cooling to separate undersized and oversized particles, ensuring uniform particle size in finished products.
2. Bio-Organic and Organic–Inorganic Compound Fertilizers – Enables precise particle size classification for mixed fertilizers, improving consistency and appearance while reducing packaging blockages.
3. Composting and Agricultural Waste Recycling – Ideal for grading fertilizers derived from straw, livestock manure, or garden waste, effectively removing lumps and oversized particles to enhance utilization efficiency.
4. Compound Fertilizer and Chemical Materials Processing – Beyond organic fertilizers, the classifier is also applicable for grading compound fertilizers, chemical powders, feed granules, and construction materials, demonstrating broad industrial adaptability.
5. Pilot and Laboratory Systems – Compact classifier units can be used in R&D institutions or pilot plants for formula optimization and test production verification.
